Mädchen Amick (/ˈmeɪdʃən ˈeɪmɪk/ MAYD-shən AY-mik; born December 12, 1970) is an American actress. She is best known for her role as Shelly Johnson on the cult television series Twin Peaks (1990–1991, 2017) and its prequel film Twin Peaks: Fire Walk with Me (1992). She is also known for her role as Tanya Robertson in Stephen King's Sleepwalkers (1992). Amick currently portrays Alice Cooper in Riverdale (2017–present).
Amick was born in Sparks, Nevada, a few miles east of Reno, the daughter of Judy, a medical office manager, and Bill Amick, a musician. Amick's parents are partly German; the name Mädchen (German: ( listen)), which means "girl" or "maiden" in German, was chosen by her parents, because they wanted an unusual name. She is also of Norwegian, Swedish, English and Irish descent. As a young girl, Amick was encouraged by her parents to follow her creative instincts. She learned to play the piano, bass, violin and guitar and took lessons in tap, ballet, jazz and modern dance. In 1987, at the age of 16, she moved to Los Angeles to pursue a career in acting.
